Prof. Wolkow and his co-workers at the University of Alberta in Edmonton, Canada have created the most dense, solid-state memory in history using scanning probe microscopy techniques.

The new discovery for atomic-scale rewritable memory allows for the creation of small, dense memory at the atomic-scale which is also stable at room temperature. Such devices are created by atom manipulation in combination with efficient error correction/editing based on machine learning methods. These new techniques have been used to control the tip for automated error-free device fabrication in a Scienta Omicron LT STM at 4 Kelvin.
